Valve device of hermetic compressor

Abstract

The invention discloses a valve device of closed-type compressor, which consists of drainage valve 150a and coat pad 220, wherein the drainage valve 150a covers the outlet 110b of valve board 110, which switches the outlet 110b selectively; the coat pad 220 is set between the drainage side of valve board 110 and covered valve board 110 and roof plate 170 to separate the sucked coolant and drained coolant, which forms the stop 300 on one side to control the starting degree of drainage valve 150a. The invention reduces the assemblage procedure of closed-type compressor valve device, which improves the production efficiency and reduces the making cost of compressor.

Description

technical field [0001] The present invention relates to a hermetic compressor, more specifically, to a valve device for a hermetic compressor that controls the suction and discharge of refrigerant from a cylinder. Background technique [0002] The hermetic compressor includes a compression mechanism that reciprocates to compress refrigerant, an electric mechanism that supplies power to the compression mechanism, and a hermetic container that accommodates the compression mechanism and the electric mechanism. Such a hermetic compressor is one of the basic components of refrigeration systems such as refrigerators, and plays a role in converting low-temperature and low-pressure gaseous refrigerants into high-temperature and high-pressure gaseous refrigerants. Also, such state change is effected by the compressive force of the piston reciprocating inside the cylinder.

AI Technical Summary

Problems solved by technology

That is, the structure of the valve device 11 is too complicated

In this way, a plurality of components increases the number of assembly processes corresponding to the number, so there is a disadvantage that the assembly process becomes complicated due to the plurality of components.

[0018] In addition, many components must be produced separately, so there is a disadvantage that the production cost of the compressor will eventually increase.

In addition, the increase in assembly processes and the extension of working hours eventually lead to a decrease in compressor production efficiency

[0019] In addition, in the process of discharging the refrigerant, the discharge valve 23 and the valve spring 25 collide with each other, and impact noise is generated.

This increases the noise of the hermetic compressor in operation, which eventually leads to an increase in the noise of refrigerators that mainly use hermetic compressors.
